Method, system and equipment for automatic neighbor relation establishment

Abstract

The invention discloses a method, system and equipment for automatic neighbor relation establishment. The method comprises the steps that a serving base station receives a measurement report, which carries a PCI (physical cell identifier) of a target cell, from a terminal device and sends a request message, which is used for obtaining neighbor relation information and carries the PCI of the target cell, to a management station if a neighbor relation with the target cell is not established currently, and the management station determines the neighbor relation information of the target cell by using the PCI of the target cell; and the serving base station receives a response message, which is used for informing the neighbor relation information and carries the neighbor relation information of the target cell, from the management station and establishes the neighbor relation with the target cell by using the neighbor relation information of the target cell. According to the method, the system and the equipment, the process for establishing automatic neighbor relations can be simplified, the number of messages during the establishment of the automatic neighbor relations is reduced, the time for establishing the automatic neighbor relations is reduced, and the handover success ratio of terminal devices is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for establishing an automatic neighbor relationship. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the establishment of the neighbor relationship is very complicated, and it is difficult to manually establish the neighbor relationship. Therefore, ANR (Automatic Neighbor Relation, automatic neighbor relationship) is currently used to realize the neighbor relationship Established to reduce manual handling of neighbor relationships, increase the number of successful handovers, and reduce dropped calls due to lack of neighbor relationships. [0003] Such as figure 1 As shown, it is a schematic diagram of establishing a neighbor relationship based on ANR in an LTE system, and the process includes: [0004] Step 1. After the terminal device is attached, if it finds an unknown neighbor cell dur...

Problems solved by technology

Specifically, after the terminal device reports the PCI of the target cell, it needs to read the SIB1 broadcast by the target cell according to the instruction of the serving base station. There are 4 messages (that is, step 4 and step 5) to establish a neighbor relationship between base stations, about 10ms; therefore, it takes 60ms to establish a neighbor relationship in the prior art, and the time to establish a neighbor relationship is relatively long
